Rated 5 out of 5Â by KatieZoe 9-Cell Battery
What a difference the 9-cell battery makes! I'm just sorry that I didn't make this purchase sooner.
Possibly HP could offer this as an option on the initial purchase of a laptop?

Rated 4 out of 5Â by cheyguy More cells good?
Bought a dv6t with i7-2670 for my son, and following the "common knowledge", got a 9-cell to go with the standard 6-cell. Installed the 9-cell, and got about 4-1/2 hours out of it, installing software and "testing". My Toshi, which I liked very much, had a 12-cell, but it had an i7-740 processor, and would only last about 2 to 2-1/2 hours. So this was a definite upgrade. And so I bought a nearly identical dv6t for me. Then I "tested" the 6-cell, and it ran just under 4 hours, still a significant increase in running time without having to plug in. I ran Office 2010 Home & Business, Adobe Photoshop CS5, Norton 360, and lots of online researching (my hobby in retirement). So yes, I think it is a good investment to get the 9-cell, and I'll keep the 6 as a backup. Don't know if a 12-cell would make a difference to the dv6t (if one were offered), but I prefer the smaller bump (raises the typing surface just enough to minimize wrist angle) on the 9 to the 12's larger one (minor quibble). I like the dv6t so far, and the 2nd Gen Intel processor, and it's nice to be able to go longer between charges when I travel. I did buy the car charger, so that's not a problem, but the longer time between charges is still one less hassle of a laptop.

Rated 5 out of 5Â by FranktheRaven Finally a long lasting battery
I can finally run a laptop like it should be, that is, on battery power. I get about 4 hrs worth. The bump that the 9-cell battery has under the computer is not an issue. The 3 year warranty is also great. Very satisfied.

Rated 5 out of 5Â by SatisfiedSue HP 9-cell Extended Life Battery MU09
HP advertises that this products gives approx. 8 hours of battery use. I usually get a little longer than that and I have a high-end laptop with heavy graphics. I am a Web design/developer.
I HIGHLY recommend this battery - I have TWO of them!!

After my initial laptop battery died, I had to get a new one. This 9-cell battery could last forever. I love it!. A+
